玄武岩纤维透水沥青混合料的配合比设计
|
摘要
为了分析玄武岩纤维长度对透水沥青混合料配合比设计指标的影响,通过谢伦堡析漏试验确定不同长度玄武岩纤维透水沥青混合料的最佳油石比,采用马歇尔试验研究了马歇尔指标随玄武岩纤维长度的变化规律。试验结果表明:玄武岩纤维透水沥青混合料的最佳油石比随掺入玄武岩纤维长度的增加而提高;玄武岩纤维提高了透水沥青混合料的力学性能,改善了透水沥青混合料的稳定度和流值;掺入玄武岩纤维的透水沥青混合料的空隙率和连通空隙率相对普通透水沥青混合料有所变化,但差值较小,玄武岩纤维对透水沥青混合料的空隙率影响不明显。
In order to analyze the influence of basalt fiber length on the mix design index of permeable asphalt mixture,the optimum asphalt-aggregate ratio of permeable asphalt mixture with different basalt fiber length was determined by Schellenberg leak test,and the change rule of Marshall index with the length of basalt fiber was studied by Marshall test.The test results show that the optimum asphalt-aggregate ratio of basalt fiber permeable asphalt mixture increases with the increase of the length of basalt fiber.Basalt fiber improves the mechanical properties of permeable asphalt mixture,as well as the stability and flow value.The void ratio and connected void ratio of permeable asphalt mixture mixed with basalt fibers fluctuate with little difference compared with common permeable asphalt mixture,and have no obvious influence on the void ratio of permeable asphalt mixture.
